Description

Technical Field

[0001] The invention relates to the technical field of vehicle frame processing, and in particular to a cutting device for vehicle frame production. Background Art

[0002] The automobile frame is the basic structural component of the automobile and the skeleton of the automobile. It is used to support and install automobile engines, bodies, chassis and other assemblies and parts, bear the load of the automobile, and ensure the accurate relative positions of various assemblies and parts. The main raw materials of automobile frames include high-strength steel plates, galvanized thin steel strips, aluminum alloys and carbon fibers. When using steel plates to produce automobile frames, it is necessary to splice two steel plates or connect the two ends of a steel plate. Therefore, it is necessary to use welding equipment to weld the steel plates. Before welding, in order to ensure the welding quality, the ends of the two steel plates need to be cut.

[0003] A Chinese patent application document with publication number CN119609206A discloses a metal sheet cutting device, which includes a workbench, two cutting tables are arranged on the top of the workbench, a metal sheet is placed above the cutting tables, a cutting blade is arranged directly above the metal sheet, mounting frames are fixedly installed on both sides of the workbench, a fixed table is fixedly connected between the two mounting frames, a hydraulic cylinder is fixedly installed on the top of the fixed table, the output end of the hydraulic cylinder is fixedly connected to the top of the cutting blade, connecting rods are fixedly connected on both sides of the cutting blade, one end of the connecting rod is fixedly connected with an inner sliding block 1, and the two inner sliding blocks 1 are respectively slidably connected to the two fixed tables, lifting components are arranged on both sides of the cutting blade, the lifting components are used to drive the two cutting tables to tilt, a vibration component is arranged inside the lifting component, the vibration component is used to vibrate the cutting table during the tilting process, and an external positioning component is arranged above the cutting table.

[0004] However, the structural design of the above-mentioned related technology: although the debris can be cleaned after cutting, the angle of the cutting blade used to cut the plate is fixed. When cutting, it is inconvenient to detect the inclination of the end of the steel plate, and thus it is inconvenient to adjust according to the inclination of the end of the other plate, resulting in that the ends of the two plates need to be cut before welding, which easily causes waste of materials and increases production costs.

[0005] Therefore, we propose a cutting device for frame production to solve the above-mentioned problems. Summary of the invention

[0006] The present invention provides a cutting device for frame production, aiming to solve the problem in the related art that when cutting steel plates, two steel plates need to be cut, which easily causes material waste.

The cutting device for frame production also comprises: The angle detection mechanism includes a lifting plate guided and assembled on the support frame along the up-down direction, and also includes a rotating rod installed on the lifting plate and rotating around an axis extending up and down, and two detection rods are arranged on the rotating rod, and the two detection rods are used to be pushed by the two sides of the end of one of the steel plates to drive the rotating rod to rotate, and installation boxes are installed on both sides of the lifting plate, and detection plates are elastically slidably connected to the two installation boxes along the transverse direction, and the detection plates are in contact with the top of the guide plate to detect the position of the other end of the steel plate; A cutting mechanism is guided and assembled on the support frame in the up-down direction, and is used to cut the end of another steel plate. The cutting mechanism includes a cutting knife that is used to rotate around an axis extending up-down; The transmission assembly connects the rotating rod and the cutting knife. When the rotating rod rotates, the cutting knife is driven to rotate synchronously through the transmission assembly.

[0008] The ends of the two steel plates are conveyed to the guide plate through two feeding assemblies. During the conveying process, the two detection rods are pushed by the two sides of the end of one of the steel plates to drive the rotating rod to rotate. At the same time, the rotating rod drives the cutting knife to rotate so that the angle of the cutting knife is the same as the inclination angle of the end of the detected steel plate. During the detection process, the two detection plates detect the position of the end of the other steel plate. When the two detection plates are in contact with the end of the other steel plate, the cutting knife cuts the end of the other steel plate to make the inclination angles of the two steel plate ends the same.

[0009] Preferably, a driving assembly is provided on one side of the top of the support frame, a locking assembly is connected to the driving assembly, the locking assembly is provided on the top of the cutting knife, and the driving assembly drives the cutting knife to rise and fall through the locking assembly; The locking assembly includes a connecting seat arranged at the top of the cutting knife, the driving assembly includes a connecting shaft located at the bottom, the connecting shaft is rotatably connected to the connecting seat, and the locking assembly also includes two limit members arranged on the connecting seat, the two limit members clamp the connecting shaft after the cutting knife rotates into place to prevent the cutting knife from rotating.

[0010] When both detection plates are in contact with the ends of the steel plate, the driving assembly drives the cutting knife to move downward to cut the ends of the steel plate. During the downward movement of the cutting knife, the two limit members clamp the connecting shaft to prevent the cutting knife from rotating.

[0011] Preferably, a horizontal plate is fixedly mounted on the support frame, a fixed cylinder is fixed on the horizontal plate, a rotating rod is fixed on the top of the cutting knife, the connecting seat is fixed on the rotating rod, and the rotating rod penetrates into the fixed cylinder; The limiting member includes a limiting rod slidably mounted on the inner wall of the connecting seat, a clamping plate is fixed to one end of the limiting rod located at the connecting seat, and an elastic member 2 is pressed between the clamping plate and the connecting seat. After the connecting seat moves down to the fixed tube, the limiting rod is pressed by the inner wall of the connecting seat so that the clamping plate clamps the connecting shaft.

[0012] When the cutting knife moves downward, the connecting seat gradually enters the fixing tube, the fixing tube squeezes the limiting rod, and the limiting rod drives the clamping plate to approach the connecting shaft to clamp the connecting shaft.

[0013] Preferably, the transmission assembly comprises a transmission wheel 1, a transmission wheel 2, a rotating shaft, a gear 1, a gear 2 and a gear 3, wherein the transmission wheel 1 is installed on the outside of the rotating rod, the transmission wheel 1 and the transmission wheel 2 are connected via a belt transmission, a rotating shaft is installed in the middle of the transmission wheel 2, the rotating shaft is rotatably connected to one side of the bottom of the lifting plate, and the gear 1 is installed at the bottom end of the rotating shaft; The gear 2 is fixed on the rotating rod, the gear 3 is rotatably mounted on the horizontal plate, and the gear 3 is meshed with the gear 1 and the gear 2 at the same time.

[0016] When the driving assembly drives the cutting knife to move downward, the lead screw 2 drives the threaded plate 2 to move downward. At this time, under the support of the detection rod and the mounting box, the connecting frame connected to the lifting plate does not move. After the cutting knife cuts the steel plate, the driving assembly first drives the cutting knife to move upward until it is reset, and then the driving assembly continues to drive the cutting knife to move upward. When the cutting knife continues to move upward after being reset, the threaded plate 2 drives the lifting plate to move upward through the connecting frame, and the lifting plate drives the detection rod and the detection plate to move upward, so as to avoid affecting the subsequent transportation of the steel plates.

[0017] Preferably, the driving assembly includes a lead screw 1, and a transmission wheel 3 is installed on the outer side of the top end of the lead screw 1 and the outer side of the top end of the lead screw 2, and the two transmission wheels 3 are connected by a belt drive.

[0019] During the contact between the detection plate and the steel plate, the elastic part will gradually compress. When the detection plate moves up, the detection plate gradually separates from the end of the steel plate. At this time, the elastic part will reset, and at the same time, the elastic part will drive the detection plate to reset through the sliding sleeve to facilitate the next detection.

[0020] By adopting the above technical scheme, the beneficial effects of the present invention are as follows: in the process of the two feeding assemblies driving the ends of the two steel plates to convey to the guide plate, the two detection rods are pushed by the two sides of the end of one of the steel plates to drive the rotating rod to rotate, and at the same time the rotating rod drives the cutting knife to rotate so that the angle of the cutting knife is the same as the inclination angle of the end of the detected steel plate. During the detection process, the two detection plates detect the position of the end of the other steel plate. When the two detection plates are in contact with the end of the other steel plate, the driving assembly drives the cutting knife to cut the end of the other steel plate, so that the inclination angles of the two steel plate ends are the same, which is convenient for splicing the two steel plates. During cutting, only one steel plate needs to be cut, thereby reducing material loss. BRIEF DESCRIPTION OF THE DRAWINGS

The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0030] like Figures 1 to 7 As shown, the cutting device for frame production of the present invention includes a base 11, and a welding assembly 21 is installed on one side of the top of the base 11. In this embodiment, the welding assembly 21 is a welding robot. In other embodiments, the welding assembly 21 is a handheld welding gun for welding steel plates. Two feeding assemblies 31 are arranged on the other side of the top of the base 11 to drive the two steel plates to approach each other. A guide plate 33 is arranged between the two feeding assemblies 31. A support frame 34 is arranged on the top of the two feeding assemblies 31. An angle detection mechanism is arranged on the support frame 34. The angle detection mechanism includes a detection assembly 1 41 and a detection assembly 2 44. The detection assembly 1 41 and the detection assembly 2 44 are respectively arranged on both sides of the top of the guide plate 33 to detect the end face of the steel plate. A cutting mechanism is arranged on one side of the inner wall of the support frame 34 to cut the end of the steel plate. The cutting mechanism is provided with a driving mechanism.

[0031] The two feeding components 31 convey the ends of the two steel plates to the guide plate 33. During the conveying process, the detection component 41 detects the end of one of the steel plates and adjusts the angle of the cutting mechanism so that the angle of the cutting mechanism is the same as the inclination angle of the end of one of the steel plates. Then the driving mechanism drives the cutting mechanism to cut the end of the other steel plate so that the inclination angles of the ends of the two steel plates are the same, which is convenient for splicing the two steel plates. When cutting, only one steel plate needs to be cut, thereby reducing material loss.

[0032] like Figure 1 to Figure 2 As shown, the detection component 41 includes a mounting plate 411, a rotating rod 413 and two detection rods 412. The mounting plate 411 is mounted on the bottom end of the rotating rod 413. The two detection rods 412 are respectively mounted on both sides of the bottom of the mounting plate 411.

The transmission wheel 1 421 is installed on the outer side of the rotating rod 413, and the transmission wheel 1 421 and the transmission wheel 2 422 are connected by belt transmission. A rotating shaft 423 is installed in the middle of the transmission wheel 2 422, and the top end of the rotating shaft 423 is rotatably connected to the bottom side of the lifting plate 43, and the gear 1 424 is installed at the bottom end of the rotating shaft 423.

[0034] During the conveying process of the steel plate, when the end of the steel plate is tilted, the steel plate first contacts one of the detection rods 412. As the steel plate continues to move, the steel plate drives the mounting plate 411 to rotate through the detection rod 412, so that both detection rods 412 contact the ends of the steel plate, thereby detecting the inclination angle of the steel plate. At this time, the steel plate stops conveying, and when the ends of the steel plate are flush, the mounting plate 411 does not rotate.

[0035] like Figure 1 , Figure 2 and Figure 4 As shown, the detection component 2 44 includes two detection plates 444. In the forward direction of the steel plate end, the detection rod 412 and the detection plate 444 are located in the same straight line, the bottom of the detection plate 444 is in contact with the top of the guide plate 33, and a sliding sleeve 443 is installed on the top of the detection plate 444. The internal sliding connection of the sliding sleeve 443 is a sliding rod 1 441.

[0036] like Figure 2 and Figure 4As shown, a mounting box 445 is provided on the outer side of a slide bar 441, and two ends of the slide bar 441 are respectively installed on both sides of the inner wall of the mounting box 445, and a sliding groove 448 for sliding movement of a detection plate 444 is opened on one side of the mounting box 445. An elastic member 442 is provided on the outer side of the slide bar 441. In the present embodiment, the elastic member 442 is a spring, and the elastic member 442 is arranged between the inner wall of the mounting box 445 and the sliding sleeve 443 to drive the detection plate 444 to reset. A pressure sensor (not shown in the figure) is provided at the end of the elastic member 442. When both detection plates 444 are in contact with the end of the steel plate, the driving mechanism drives the cutting mechanism to cut the steel plate in contact with the detection plate 444.

[0037] Continue to refer Figure 2 and Figure 4 As shown, a fixing rod 446 is installed on the top of the installation box 445 , a fixing plate 447 is installed on the top of the fixing rod 446 , and the fixing plate 447 is installed on one side of the lifting plate 43 .

The connecting seat 621 is installed at the top of the rotating rod 612. The connecting seat 621 is rotatably connected to the driving mechanism. The driving mechanism drives the cutting knife 611 to move downward through the connecting seat 621. When the cutting knife 611 moves downward, the limit members enter the supporting assembly 63. At this time, under the action of the supporting assembly 63, the two limit members clamp the driving mechanism to prevent the adjusted cutting knife 611 from rotating.

[0041] like Figure 6As shown, the limiting member includes a limiting rod 622, a clamping plate 623 and an elastic member 624. The clamping plate 623 is arc-shaped and is located inside the connecting seat 621. One end of the limiting rod 622 is installed on the outside of the clamping plate 623. The other end of the limiting rod 622 passes through the connecting seat 621 and extends to the outside of the connecting seat 621. The other end of the limiting rod 622 has an arc surface. The elastic member 624 is arranged between the outside of the clamping plate 623 and the inner wall of the connecting seat 621 to drive the clamping plate 623 to reset. In this embodiment, the elastic member 624 is a spring. In other embodiments, the elastic member 624 is an elastic sheet.

[0042] like Figure 2 and Figure 5 As shown, the support assembly 63 includes a fixed cylinder 631, a horizontal plate 632 and a gear three 633. The horizontal plate 632 is installed on the outer side of the top of the fixed cylinder 631, and one side of the horizontal plate 632 is installed on the inner wall side of the support frame 34. The gear three 633 is rotatably connected to the bottom side of the horizontal plate 632. The gear three 633 can be engaged with the gear one 424 and the gear two 613 respectively.

[0043] When the cutting blade 611 moves downward, the connecting seat 621 enters the interior of the fixing tube 631 , and at this time, the fixing tube 631 squeezes the limiting rod 622 , and at the same time, the limiting rod 622 drives the clamping plate 623 to clamp on the driving mechanism.

[0044] like Figure 2 , Figures 5 to 7 As shown, the driving mechanism includes a driving component 51 arranged on one side of the top of the support frame 34, one side of the driving component 51 is transmission-connected with a driven component 52, the driving component 51 is rotationally connected to the connecting seat 621, and the driven component 52 is arranged on the other side of the top of the support frame 34.

[0045] like Figure 2 and Figure 7 As shown, the driving assembly 51 includes a fixed frame 511, a driving member 512, a screw 513 and a connecting shaft 517. The fixed frame 511 is installed on the top side of the support frame 34. In the present embodiment, the support frame 34 and the fixed frame 511 are both U-shaped. In other embodiments, the fixed frame 511 is L-shaped. The driving member 512 is installed on the top of the fixed frame 511. The top end of the screw 513 is rotatably connected to the inner top wall of the fixed frame 511. The driving shaft of the driving member 512 is installed on the top end of the screw 513. In the present embodiment, the driving member 512 is a servo motor.

[0046] like Figure 2 , Figure 6 and Figure 7As shown, the outer side of the lead screw 513 is threadedly connected to a threaded plate 514, and two slide rods 515 are installed at the bottom of the threaded plate 514. A connecting plate 516 is installed at the bottom end of the slide rod 515. The connecting plate 516 is located below the inner top wall of the support frame 34.

The connecting shaft 517 is installed at the bottom of the connecting plate 516, and the connecting shaft 517 is rotatably connected to the middle part of the inner bottom wall of the connecting seat 621.

[0047] The driving member 512 drives the connecting shaft 517 on the connecting plate 516 to move downward through the threaded plate 514 on the screw 513. At this time, the connecting shaft 517 drives the cutting knife 611 to move downward through the rotating rod 612 on the connecting seat 621 to cut the steel plate. After the cutting is completed, the waste is taken out for subsequent operations. When the connecting seat 621 enters the fixed cylinder 631, the fixed cylinder 631 squeezes the limiting rod 622, and at the same time, the limiting rod 622 drives the clamping plate 623 to clamp on the connecting shaft 517.

[0048] like Figure 2 and Figure 7 As shown, the driven assembly 52 includes a lead screw 521 rotatably connected to the top of the support frame 34, and a transmission wheel 3 518 is installed on the outer top of the lead screw 1 513 and the outer top of the lead screw 2 521, and the two transmission wheels 3 518 are connected by belt drive.

The outer side of the lead screw 521 is sleeved with a connecting frame 523, and the top of the threaded plate 522 is in contact with the inner top wall of the connecting frame 523. The bottom of the connecting frame 523 passes through the top of the support frame 34 and is installed on the top of the lifting plate 43.

[0050] When the cutting knife 611 moves downward, the lead screw 1 513 drives the lead screw 2 521 to rotate, and at the same time, the lead screw 2 521 drives the threaded plate 2 522 to move downward. When the cutting knife 611 is reset, the threaded plate 2 522 is reset at the same time. Then the driving member 512 drives the cutting knife 611 to continue to move upward through the lead screw 1 513. At this time, the threaded plate 2 522 drives the connecting frame 523 to move upward. When the connecting frame 523 moves upward, it drives the mounting plate 411 and the mounting box 445 to move upward at the same time through the lifting plate 43, so that the detection rod 412 and the detection plate 444 are separated from the steel plate, so that the two steel plates can be spliced.

[0051] like Figure 1 and Figure 2As shown, the feeding assembly 31 includes a fixed frame 311 and a plurality of conveying rollers 313. The bottom of the fixed frame 311 is installed on the top side of the base 11. The plurality of conveying rollers 313 are rotatably connected to the inside of the fixed frame 311. The plurality of conveying rollers 313 are transmission-connected to each other. One end of one of the conveying rollers 313 is connected to a first motor. The first motor on the conveying roller 313 is installed on one side of the fixed frame 311. The plurality of conveying rollers 313 are evenly distributed along the length direction of the fixed frame 311. An opening 312 is provided on one side of the fixed frame 311 to facilitate the removal of the welded steel plate.

[0052] Continue to refer Figure 1 and Figure 2 As shown, a pressing assembly 32 is provided on the fixed frame 311, and the pressing assembly 32 includes a telescopic member 321, a mounting frame 322 and a plurality of connecting rollers 323. The telescopic member 321 is installed on the top of the fixed frame 311. In the present embodiment, the telescopic member 321 is a cylinder. In other embodiments, the telescopic member 321 is a hydraulic cylinder or an electric telescopic rod. The mounting frame 322 is installed on the movable end of the telescopic member 321. The mounting frame 322 is U-shaped. The mounting frame 322 is located inside the fixed frame 311 and is arranged above the conveying roller 313. A plurality of connecting rollers 323 are rotatably connected to the inside of the mounting frame 322. The plurality of connecting rollers 323 are transmission-connected to each other. The plurality of connecting rollers 323 are evenly distributed along the length direction of the mounting frame 322. A second motor is connected to one of the connecting rollers 323, and the second motor on the connecting roller 323 is installed on one side of the mounting frame 322.

[0053] Working principle: through the rotation of the conveying roller 313 and the connecting roller 323, the two steel plates can be driven to move onto the guide plate 33. During the movement of the two steel plates, the end of one of the steel plates is detected by the detection rod 412. At the same time, the rotating rod 413 drives the gear three 633 to rotate through the gear one 424. The gear three 633 drives the cutting knife 611 on the rotating rod 612 to rotate through the gear two 613, so that the inclination angle of the cutting knife 611 and the end of the detected steel plate are the same. In the process of the detection rod 412 contacting with one of the steel plates, if the end of the other steel plate is tilted, it will first contact with one of the detection plates 444. When the two detection plates 444 are in contact with the steel plates, the driving member 512 drives the connecting shaft 517 on the connecting plate 516 to move downward through the threaded plate one 514 on the screw one 513. At this time, the connecting shaft 517 drives the cutting knife 611 to move downward to cut the other steel plate. At this time, the inclination angles of the ends of the two steel plates are the same.

[0054] When the steel plate is cut, the driving member 512 drives the cutting knife 611 to move upward through the rotation of the lead screw 1 513. When the cutting knife 611 is reset, the driving member 512 continues to drive the cutting knife 611 to move upward through the lead screw 1 513. At the same time, the lead screw 1 513 drives the threaded plate 2 522 on the lead screw 2 521 to move upward through the transmission wheel 3 518. During the upward movement of the threaded plate 2 522, the lifting plate 43 is driven to move upward through the connecting frame 523. At this time, the lifting plate 43 drives the detection rod 412 and the detection plate 444 to move above the steel plate.
